I SPECIFICATION forming part of Letters Patent N0, 520,942, dated June5, 1894.

Application led September 19,1892. Serial No. 446,276. (No model.)

To all whom it mayconcern:

Be it known that we, JOHN STEVENSON, J r., and CHARLES J. JOHNSON, bothof New Castle, in the county of ALawrence and State of Pennsylvania,have invented a new and useful Improvementin Metal-Uoiling Apparatus, ofwhich the following is a full, clear, and eX- act description, referencebeing had to the accompanying drawings, forming part ot' thisspecification, in which- Figure '1 is an elevation, partly in verticalsection, of our improved rod-coiling appara Fig. 2 is afront elevation;and Fig. 3 is a plan View, partly in section, showing the spokes of thereel.

The object of our invention is to provide a rod-coiling apparatus ofsimple construction, and adapted to permit the removal of the coil Inoreeasily than other apparatus heretofore known to us.

- In the drawings, 2 represents the last pass of the rolls of a wire-rodmill.

3 represents the usual tubular guide leading from the rolls to thecoiling apparatus, which is the subject of our invention, and 4 is-therod shown in transit from the rolls to the coiler.

The coiling apparatus proper comprises a rotary apertured coiler orlay-o 5, having a hollow neck 6 fitted within a tubular collar 7, whichforms the journal of a gear-wheel 8. The neck 6 is detachable from thelay-oft 5 and the collar 7, so that when worn out it may be replaced,and the collar is journaled in a suitable bearing 8. The coiler isrotated by gearingas shown, and its revolution eiects in the ordinarymanner the coiling of the rod, which passes therethrough from theguide-tube 3, as above explained.

The rod as it is delivered from the lay-o is coiled around a frame ordrum, which consists preferably of spokes 10, projecting from a head 11or other holding device and pass-- ing through a stationary bed-plate 12around which there may be a guard-rim 13. The spokes of the frame aremovable lengthwise through the bed-plate, so that they may be retractedto the position shown by dotted lines in Fig. l for the purpose ofpermitting the removal of the coiled rod. Such motion vmay be eiected bymeans of a lever 14 me chanically connected with a longitudinallysliding-rod 15 Xed to the head 11.

The bed-plate 12 is not horizontal as are the ordinary beds on whichwire rods are coiled around the receiving-frame or drum, but is set atan inclination so that when the frame or drum is withdrawn from the coilthe latter may slide down the face plate or may be easily pulled downthe same, the rim 13 being open at the lower end of the face-plate topermit the passage of the coil. The journal of the lay-oit has its axissubstantially at right angles to the plane of the bed-plate, and istherefore inclined somewhat from the vertical.

The operation is asfollowsz-The frame or drum is made to project beyondthe bed-plate 12, as-shown in Fig. v1, the rod propelled by the rolls isdelivered to the revolving coiler vfrom the tube 3, and is' laid in acoil around said frame or drum, which serves to effect the pulling ofthe last end through the tube 3,

Land to prevent its sticking therein when it has lost the propulsiveforce of the rolls. When the rod has been completely coiled theoperator, by motion of the lever 14, retracts the frame or drum, movingit below the level of the bed-plate 12 and releasing the coil, whereuponthe coil slides down the bedplate upon a receiver, preferably consistingof an endless conveyor 16, which operates to carry it oft to anotherplace in the mill. The frame or drum may thenV be projected again inreadiness to receive another coil. In order to 'confine the first end ofthe rod, if it should be delivered by the lay-oft at the point adjacentto the opening at the foot ot with a second series of spokes 1S, situateat this place and projecting through the bedplate outside the path ofrotation of the layoff, so that the rod shall be coiled between thespokes 10 and 18, and shall )be held in place by the latter.

vthe rim 13, we prefer to provide the head 1l The advantages of ourinvention will be IDO relative arrangement of the parts may be made bythose skilled in the art without involving departure from our inventionas stated in the following claims, each of which sets forth an item ofinvention unqualified by limitations peculiar to other claims.

l. In metal-coilin g apparatus, the combination witha coiler, of areceiving-bed on which the metal is coiled; said bed being inclined tothe horizontal at an angle between ninety degrees and the limiting angleof friction between the bed and the metal substantially as described.

2. In metalcoiling apparatus, the combination with a coiler, of areceiving-bed on which the metal is coiled, and means constructed tohold said coil during the act of ceiling, and to release it at theconclusion thereof said bed being inclined to the horizontal at an angle between ninety degrees and the limiting angle of friction betweenthe bed and the metal; substantially as described.

3. In metal-coiling apparatus, the combination of a rotary coiler, areceiving-bed, and a drum or frame movable therethrough; said bed beinginclined to the horizontal at an angle between ninety degrees and thelimiting angle of friction between the bed and the metal substantiallyas described.

4. In metal-coiling apparatus, the combination of a rotary coiler, areceiving-bed, a drum or frame, and an inclosing rim; said bed beinginclined to the horizontal at an angle between ninety degrees and thelimiting angle of friction between the bed and the metal substantiallyas described.

5. In metal-coiling apparatus, the combination with a rotary coiler, ofa receiving-bed, a drum or frame movable therethrough, and an outerrod-confining frame between which and the drum or frame first named therodis coiled; said bed being inclined to the horizontal at an anglebetween ninety degrees and the limiting angle of friction between thebed and the metal substantiallyas described.

6. In metal-coiling apparatus, the combina tion of a rotary coiler and areceiving-plate or bed, inclined to the horizontal at an angle betweenninety degrees and the limiting angle of friction between the bed andthe metal said coller being journaled on an axis substantially at rightangles thereto; substantially as described.

7. In metal-ceiling apparatus, the combination with a coiler, of areceiving-bed on which the metal is coiled, and a conveyer at the lowerend thereof; said bed being inclined to the horizontal at an anglebetween ninety degress and the limiting angle of friction between thebed and -the metal substantially as described.

8. In metal-ceiling apparatus, the combination of a rotary coiler, aninclined receivingbed, a movable drum or frame, an inclosing rim open atthe lower end, and a movable outer rod-confining frame opposite saidopen end; substantially as described.

In testimony whereof we have hereunto set our hands this 13th day ofSeptember, A. D. 1892.
